Answer 2

Answer:

A buy it $250 Rs.$

Step-by-step explanation:

Given:

$'a'$ ring sold it to $b$ at $100$% profit.  $b$ sold it to $C$ at $20$% at loss if $C$ paid $220Rs.$

Find:

The $'a'$ buy it.

Solution:

Let the CP of $A$ is $100.$

So, A sold it to be $'b'$ at $10$%

So, CP of $B$ is $110.$

$'B'$ sold it to $C$ is at $20%$%

So, CP of $C$ is $110-22$

$=88Rs$

Now,

$'C'$ paid $220Rs.$

$88 \rightarrow 220Rs$

$1Rs=\frac{220}{88}$

$\Rightarrow 2.5Rs$

Cost price of $A$ is $100.$

So, the $'A'$ buy it $=100 \times \frac{2.5}{10}$

$=250Rs$
